PREFACE. 


This  little  book,  the  first  of  our  Series  of  Arithmetics,  presup- 
poses no  knowledge  of  numbers  whatever.  It  tries  to  give  a  cor- 
rect idea  of  their  value,  both  absolute  and  relative,  by  treating 
them  concretely  as  well  as  abstractly  from  the  very  outset,  pictorial 
illustrations  being  freely  used  for  that  purpose.  We  have  not 
sought  in  its  pages  to  go/ar,  but  to  go  thoroughly.  It  is  therefore 
confined  to  the  four  fundamental  operations,  a  very  brief  view  of 
fractions,  the  most  important  tables  of  moneys,  weights,  and  meas- 
ures, and  easy  exercises  under  them.  These  subjects,  it  is  believed, 
are  so  treated,  as  to  make  the  young  pupil  think  for  himself,  and  to 
lay  the  right  kind  of  foundation  for  a  mathematical  course.  One 
thing  is  taught  at  a  time,  and  great  care  has  been  taken  to  present 
every  thing  in  its  proper  place.  It  will  be  observed  that  through- 
out the  book  slate  exercises  go  hand  m  hand  with  mental  opera- 
tions. In  the  author's  opinion,  they  are  indispensable,  from  the 
first,  for  inspiring  the  beginner  with  that  interest  in  the  subject 
which  is  essential  to  success. 

This  book  imposes  no  labor  on  the  teacher,  in  the  way  of  ex- 
plaining orally,  furnishing  examples,  &c.  It  is  thought  to  contain 
in  itself  all  that  is  needed.  The  author  would  only  ask  those  who 
use  it  to  be  sure  that  every  lesson  is  thoroughly  mastered,  before 
proceeding  to  the  next.  Each  principle  presented,  each  table, 
should  be  perfectly  understood  and  memorized  before  leaving  it, 
even  though  it  be  necessary  to  repeat  the  lesson  again  and  again. 
Time  saved  by  allowing  a  single  lesson  to  pass  unmastered,  will 
be  a  tenfold  loss  in  the  end. 

The  Roman  Notation  is  not  explained  in  this  volume ;  but  by 
means  of  the  numerals  used  in  the  lesson-headings  the  pupil  may 
readily  be  made  to  understand  it. 

Entered,  according  to  Act  of  Congress,  in  the  year  1863,  by 

D.   APPLETON  &  CO., 

In  the  Clerk's  Office  of  the  District  Court  of  the  United  States  for  the 

Southern  District  of  New  York.

LESSON    VIII. 

Learn  tliis  table  : — 


20  is  2  tens. 
30  is  3  tens. 
40  is  4  tens. 
50  is  5  tens. 


60  is  6  tens. 
70  is  7  tens. 
80  is  8  tens. 
90  is  9  tens. 


Which  figure  shows  the  number  of  tens  ? 
Answer,  The  second,  or  left-hand  figure. 

What  is  the  second  place  called  ? 
Answer.  The  place  of  tens. 

What  is  the  first,  or  right-hand  place  called? 
Answer.  The  place  of  units. 

Write  down  22.     What  figures  do  you  use  ? 

Have  these  twos  the  same  value  ? 
Answer.  No.     The  2  in  the  second  place  is 
ten  times  as  great  as  the  2  in  the  first  place. 

Why  is  this  ? 

Answer.  Because  the  2  in  the  second  place 
denotes  two  tens^  or  twenty ;  the  2  in  the  first 
place  denotes  two  units^  or  two. 

What,  then,  is  the  efiPect  of  removmg  a  figure 
from  the  first  place  to  the  second  ? 

Answer.  Its  value  is  increased  ten  times ;  20 
is  ten  times  as  great  as  2. 

Write  down  the  numbers  from  1  to  100. 


UNITS. TENS.  11 


LESSON    IX. 

How  do  you  write  six  tens  ? 

Ans,  6  in  the  second  place  denotes  six  tens. 
As  there  are  no  units,  I  put  a  0  after  it — 60. 

How  do  you  write  six  tens,  one  unit? 

Ans.  6  in  the  second  place  denotes  six  tens  ; 
1  in  the  first  place  denotes  one  unit — 61. 

Read  this  number.  Ans.  Sixty-one. 

How  must  a  column  of  numbers  be  written  ? 
A?is.  So  that  units  may  stand  under  units,  and 
tens  under  tens. 

Write  the  following : — Four  tens,  three  units ; 
nme  tens,  nine  units ;  three  tens,  seven  units ; 
eight  tens,  two  units ;  five  tens,  two  units ;  two 
tens,  five  units ;  one  ten  ;  seven  tens. 

Eead  the  numbers  just  written. 

Mention  the  tens  and  units  in  the  following 
numbers,  and  then  read  them : — 80  {eight  tens^ 
eighty) ;  75  (seven  tens^  five  units,  seventy-five) ; 
69;  93;  41;  28;  7;  50;  17;  32;  84;  22;  61;

LESSON    X. 

How  miicli  do  10  tens  make  ? 

Ans,  One  hundred — 100. 

Which  figure  shows  the  number  of  hundreds  ? 

Ans,  The  third  figure — 1. 

How,  then,  do  we  write  two  hundred  ? 

Ans.  By  putting  a  2  in  the  third  place — 200. 

Learn  the  hundreds : — 


One  hundred  100

How  many  times  greater  is  1  in  the  third 
place  than  1  in  the  second  place  ? 

Ans.  Ten  times  ;  100  is  ten  times  10. 

What  is  the  efiect,  then,  of  removing  a  figure 
one  place  to  the  left  ? 

Ans,  Its  value  is  increased  ten  times. 

Name  the  places,  going  from  right  to  left. 

Ans.  Units,  tens,  hundreds.

"When  we  count,  one^  two^  three ^  four^  cfcc, 
how  do  we  get  each  number  ? 

Ans,  By  adding  1  to  the  number  going  before. 
Now  in  stead  of  adding  1,  add  2  each  time : 

1  7        13        19        25  31  37

In  adding  units,  if  the  sum  is  9,  what  do  we  do  ? 

Ans,  We  write  the  9  in  the  units'  place. 

If  the  sum  is  10,  what  do  we  do  ? 

Arts,  10  consists  .  of  0  units,  1  ten.  6 
Hence  we  write  0  in  the  first  or  units'  place,  _f 
and  1  in  the  second  or  tens'  place.  1^ 

Whenever  the  sum  consists  of  two  figures,  how 
must  we  place  them  ?

Look  at  this  example.  The  lower  number  is 
the  smaller ;  hence  it  can  be  taken  from  the  upper. 

Always  begin  to  subtract  at  the  right. 

9  from  2. — We  can  not  take  9  from  2,  because 
9  is  greater  than  2.  So  we  add  10  to  the  2, 
making  it  12.  9  from  12  leaves  3.  Write  down  3 
for  the  first  figure  of  tlie  remainder. 

Now,  to  balance  the  10  units  just  added  to  3 
in  the  upper  line,  add  1  ten  to  the  7  tens  in  the 
lower  line, — making  8.     Subtract  8. 

8  from  5. — We  can  not  take  8  from  5.  So 
add  10  to  the  5,  making  it  15.  8  from  15  leaves

LESSON    LXVIII. 

Multiply     734 
By  6 


Look  at  the  above  example.  Always  begin  to 
multiply  at  the  right. 

6  times  4  -  is  24 — 4  units  and  2  tens.  Write 
the  4  units  in  the  units'  place,  and  add  the  2  tens 
to  the  next  product. 

6  times  3  tens  are  18  tens,  and  2  tens  are  20 
tens — or  2  hundreds.  "Write  0  in  the  tens'  place, 
and  add  2  hundreds  to  the  next  product. 

6  times  7  hundreds  are  42  hundreds,  and  2 
hundreds  are  44  hundreds.     Answer,  4404. 

When,  in  multiplying  by  a  single  figure,  we 
get  a  product  expressed  by  two  figures,  what  must 
we  do  with  them  ? 

Ans.  We  must  place  the  right-hand  figure  of 
the  product  under  the  figure  multiplied^  and  add 
the  left-hand  figure  to  the  next  product. 

If  36  is  your  product,  what  do  you  do  with 
each  figure  ?     If  63  ?     If  72  ?

LESSON     LXZI. 

Multiply  509  by  18.     Let  us  see  how 
509       we  are  to  multiply  by  two  figures. 
_z_  "Write  18   under   509,   units  under 


4072        units,  tens  under  tens. 
^^^  18  consists  of  8  units  and  1  ten.  "We 

9162  therefore  multiply  first  by  8  units,  and 
then  by  1  ten,  and  add  the  two  prod- 
ucts. ^ 

Multiplying  by  8  units,  as  already  shown,  we 
get  4072  for  the  product. 

Now  multiply  by  1  ten.  Once  9  is  9.  Write 
it  in  the  tens'  jplace^  because  you  are  multiplying 
by  1  ten^  not  1  unit.  Once  0  is  0.  Once  5  is  5. 
The  product  is  509  tens, 

Now  add  the  two  products.     Answer,  9162. 

When  multiplying  hy  a  figure  in  the  tens'
